This was the last week of the project. We had already built the device but we had to program it so that it can follow a black line using its light sensor. This was quite hard to figure out because we didn't have a guide, unfortunately i wasn't able to finish as i was struggling to make it follow the line.

Unfortunately, we are now coming to an end with the building part of this project because we have built the line follower. The idea is to build a buggy to follow a black line so that it can successfully lap a circuit on a board, to do this we will need to create a program to drive the nxt. As we just finished building the nxt we didn't have time to create a program. Next week we will be doing this, I expect this to be really hard....

This week we had to build the actual device. In other words, a line follower. This was definitely the fun part of the project because we are using lego to build a machine! We used and instruction booklet to do this. The idea is to build a buggy to follow a black line so that it can successfully lap the circuit on the board. This uses a light sensor to track the line.

This week we finally finished our pilots and we moved on to doing the exercise before starting to build the system. In the final exercise  we had to create a pilot without instructions. It took us quite a few attempts but we were able to finish it. Then we moved on to building the system, we had to make a line follower. This had to follow a line on a board using motors and sensors.

This week we were on our final task before starting to build the actual device. This was quite tricky because it told us what we had to create but no steps on how to do it. We had to use our general knowledge on how the nxt worked. We had to create something similar to pilot 4 but more of a challenge. In the end we managed to create it, this took us a few goes to complete, so unfortunately we didn't have time to start building the device. Next lesson we will be building the device.

We used ROBOLAB to switch off and on lamps and we learnt how to use the touch sensor. The sensor which opened my eyes was the light sensor because on the actual device itself it tells you how dark it is by percentage. 

On week 4 we carried on using ROBOLAB and got use to the different components which the NXT has to offer. Last week we had finished pilot 1& 2 so this week we are moving on to pilot 3 & 4. We used ROBOLAB to switch off and on lamps and we learnt how to use the touch sensor. The sensor which opened my eyes was the light sensor because on the actual device itself it tells you how dark it is by percentage. The picture on the right is an example of the different pilots we are doing
